d . Pale castaneous, with parts of elytra paler. Moder- 

 ately clothed with short, white pubescence, becoming setae at 

 apex of elytra, and absent from the middle of prothorax and 

 elytra. 



Head with a few more or less concealed subrugose punc- 

 tures and two large shallow foveae between the eyes. 

 Antennae long and moderately stout, the first two joints about 

 twice as wide as joints three to seven, the first about as 

 long as second and third combined, the 

 second little more than half the length of 

 the first, third to seventh are equal in 

 length, each being slightly longer than 

 half the length of the second, the eighth 

 cylindrical, and about as long as joints 

 three to seven combined, and as wide as 

 the second, the ninth about two-thirds 

 the length of the eighth and wider at 

 apex than at base, the tenth perceptibly 

 longer than the ninth, and the apical 

 joint about as long as the tenth, wide 

 near the base and obtusely pointed. 

 Prothorax about as wide as long, narrower 

 at apex than at base, with a few scattered 

 punctures, and a moderately large subbasal fovea. Elytra at 

 base distinctly wider than prothorax, the margins sloping out- 

 wards towards apex, a longitudinal furrow on each elytron, 

 starting from about midway between the suture and humeral 

 angle, thence to the apex, and with a short subsutural stria; 

 with minute scattered punctures. Metasternam with a deep 

 furrow starting from near the coxae of the intermediate legs 

 and touching the coxae of the posterior ones. A bdomen, dorsal 

 surface with a few small punctures arranged in transverse 

 rows, ventral surface impunctate, the third segment large 

 with very small and shallow round foveae. Legs long and 

 moderately thin, the anterior tibiae strongly curved, the inter- 

 mediate slightly curved, and the posterior ones almost 

 straight, all are dilated towards the apex. Length ( d" , 9)>
